Well one movie I can recommend for air combat scenes is “The Hunters.” It’s an old movie about the Korean War. It’s cheesey in some of the scenes but the air combat between the American and North Korean or Chinese migs are pretty damn good. They actually use Sabres in the movie and the mig-15s are I believe replicated by some old British trainer aircraft used back in the day. They do a real good job with the trainers playing migs that I remember thinking “nice.”
Another good series (not movie) is the Dogfight series from the History Channel. Was made I believe back in mid-2000s. Each episode is about a certain air battle in history covering either WW1, WW2, Korean War, Vietnam, Gulf War etc. They even have episodes on Arab-Israeli Wars. Really well done stuff and plenty of just pure air combat. Below is one episode from the series. You can generally find this series anywhere including Netflix etc. Well worth the watch if you haven’t seen it.
If I think of more, I’ll post here.
